Abstract

Utilization of finish and recovery of materials for control of pollution are improved in a tow crimping process wherein an advancing tow of fibers which have been processed in an aqueous bath or series of aqueous baths is uniformly compressed in a confined space under a nip pressure of 600-1,000 lbs./in. to exude solvent-containing water from the tow, the exudate being returned to the last aqueous bath, a predetermined amount of finish is applied to the tow, the fibers are crimped in a stuffing box crimper whereby some of the finish and a small amount of residual moisture are exuded from the tow, the exudate is recovered and removed to a storage container, the exudate is re-applied to the tow at a rate corresponding to the rate of exudation and the crimped tow is collected and then dried.
